Abstract
The utility model discloses a novel PFC inductor, belonging to the technical field of magnetic elements and devices and comprising a skeleton and skeleton outer winding wires, wherein the skeleton comprises two groups of magnetic cores jointed with each other and a bracket for fixing the magnetic cores, and the skeleton outer winding wires are a plurality of independent winding groups, between two of which an insulating tape is arranged. Making full use of the remaining space of the skeleton structurally, the PFC inductor according to the utility model causes the magnetic cores to be separated from electromagnetic induction of enamel-covered wires at the joint of the magnetic cores during the operation and achieves a large number of windings and larger capacitive distribution, so that the working efficiency of the entire inductor is greatly enhanced. In order to avoid high temperature at magnetic core air gaps and lower the temperature of covered wires better, the PFC inductor simultaneously avoids the direct contact between the winding wires and the magnetic core air gaps by means of separation with a blocking strip at the joint gap of the magnetic cores, thereby being favorable for temperature rise of the inductor and enhancing product efficiency.
Description
Technical field
The utility model belongs to the magnetic elements technical field, especially relates to a kind of novel PFC inducer.
Background technology
The wire winding of traditional PFC inducer, mostly directly with stranded wire from S start the F tail for the first time with backbone winding full till; This technique for coiling skeleton remaining space fails to use fully, and magnetic core when work connects at magnetic core meets place's magnetic line of force to hinder with the sympathetic generation of enamelled wire electromagnetism, and capacitance profile is little; And cause the complete machine operating efficiency to reduce, and this kind product magnetic core air gap is bigger simultaneously, and the heat that the air gap place produces is directly transferred to the line bag, influences product efficiency.
The utility model content
The purpose of this utility model is to provide a kind of novel PFC inducer, solves the defective that prior art exists.
For achieving the above object, the utility model adopts following technical scheme:
A kind of novel PFC inducer comprise skeleton, and skeleton winds the line outward, described skeleton comprises two groups of magnetic cores that connect, and the support of fixed magnetic core, described coiling is the coiling group of some independent lines footpath rap zygonema coiling, described coiling is organized between two groups and is provided with insulating tape.
Preferred scheme is: described skeleton also comprises flap, and described flap is arranged at the place, slit that two groups of magnetic core butt joints that connect form; Described coiling group and insulating tape thereof are surrounded on described flap outer surface.
More preferred scheme is: described flap is a rubber belt.
More preferred scheme is: described flap is a nonwoven fabric belts.
The utility model compared with prior art has following advantage and beneficial effect:
PFC inducer described in the utility model for the design of coiling, adopts elder generation spaced intermediate at skeleton according to the suitable wide rubber strip of every layer of usefulness of the product design number of turns in the middle of skeleton, is beneficial to the heat radiation of magnetic core air gap place; With the rap zygonema coiling of line footpath, the both sides number of turns is good on an equal basis during coiling; Start from skeleton bottom S for every layer during coiling, tail head F finishes up from the skeleton top; Whenever around one deck bag one layer tape; With backbone winding full till; Again from tail that the top will have first with reflexed to skeleton bottom terminals.When this kind winding structure utilizes the work of skeleton remaining space, magnetic core greatly magnetic core connect the place of meeting with the enamelled wire electromagnetic induction cover out, the many capacitance profile of winding are big, and the complete machine operating efficiency is improved greatly.For the coupling magnetic line of force of better avoiding magnetic core air gap place distributes, reduce loss, reduce line bag temperature, the utility model adopts the shelves band to separate at place, magnetic core butt joint slit simultaneously, avoids coiling directly to contact with the magnetic core air gap, helps controlling the temperature rise of inductor; Improved product efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As shown in Figure 1, a kind of preferred embodiment, a kind of PFC inducer, comprise skeleton 1, and skeleton winds the line outward, and skeleton 1 comprises two groups of magnetic cores that connect, and the support of fixed magnetic core, (N1～Nn), coiling is organized and is provided with insulating tape 4 between two groups for the coiling group of some independent lines footpath rap zygonema coiling in coiling.The place, slit that the magnetic core butt joint that 1 liang of group of skeleton connects forms also is provided with rubber flap 5 (the described rubber flap of present embodiment also can be the nonwoven fabrics flap), and coiling group and insulating tape 4 thereof are surrounded on described flap outer surface.
The described PFC inducer of present embodiment for the design of coiling, adopts elder generation spaced intermediate at skeleton according to the suitable wide rubber strip of every layer of usefulness of the product design number of turns in the middle of skeleton, is beneficial to the heat radiation of magnetic core air gap place; With the rap zygonema coiling of line footpath, the both sides number of turns is good on an equal basis during coiling; Start from skeleton bottom 2 (S) for every layer during coiling, tail head F is 3 endings from the skeleton top; Whenever around one deck bag one layer tape; With backbone winding full till; Again from tail that the top will have first with reflexed to skeleton bottom terminals.When this kind winding structure utilizes the work of skeleton remaining space, magnetic core greatly magnetic core connect the place of meeting with the enamelled wire electromagnetic induction cover out, the many capacitance profile of winding are big, and the complete machine operating efficiency is improved greatly.In order better to avoid the high temperature at magnetic core air gap place, reduce line bag temperature, present embodiment adopts the shelves band to separate at place, magnetic core butt joint slit simultaneously, avoids coiling directly to contact with the magnetic core air gap, helps controlling the temperature rise of inductor; Improved product efficiency.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
